3D/VR hardware:

- VR lab, TU Bergakademie Freiberg

- CAVE: The Freiberg X-SITE (eXtreme definition Spatial Immersion and interacTion Environment) is an innovative Virtual Reality CAVE that provides visualizations in ultra-high resolution of 50 million pixels. For this, images of 25 projectors are seamlessly blended on the screens of the 4-sided CAVE. An optical tracking system with 12 infrared cameras allows for 6DOF input: head tracking, full body motion capture, finger tracking, fly stick.

- HMDs: HTC Vive, Oculus Rift

Developed and used 3D/4D modelling software:

- Realtime 3D graphics:

  • CAVE VR-software is an in-house development based on open-source libraries OpenSceneGraph and VTK;
    support for all common 3D file formats, e.g. X3D, VRML, Wavefront obj, ply

  • Unreal game engine for HMD applications - and CAVE when visual realism and special effects are important.

  • X3DOM for web applications

- Scientific Visualization:

  • Paraview for visualization and post-processing of scientific data generated in HPC simulations

- 3D Modeling:

  • Blender

- Point Cloud & Mesh Processing:

  • Mesh generation from point clouds: VisualSFM, Agisoft Photoscan

  • Mesh post-processing, e.g. polygon reduction: Meshlab

Recent/ongoing projects:

- Mining-RoX:

The goal of the Mining-RoX project is the creation of mobile robot technology to facilitate the autonomous exploration of underground mines. The robots provide detailed 3D scans of the mine and monitor environmental conditions, such as air and water quality.

- VR-based Visual Analysis of Filtration Processes:

The project aims at the development of novel data compression and visualization methods supporting an interactive analysis of very-large-scale computer simulations of filtration processes. A key approach is so-called in-situ processing where data compression methods are tightly integrated into the supercomputing simulations rather than deferring them, as usually done, to subsequent post-processing steps. Early data reduction is also key for later analysis tasks including high-detail visualizations in a Virtual Reality CAVE.


- iDeepMon:

This EIT Raw Materials upscaling project aims to develop technology for the automated inspection of mine shafts. High-resolution cameras and robotic technology such as visual-inertial odometry are combined into a prototype system to provide fast and accurate 3D scans of the shaft.
